Assessment of Quality Changes in Mackerel Scomber japonicus During Refrigerated Storage: Development of a Freshness Indicator

RANCIDITY DEVELOPMENT DURING MACKEREL (Scomber scombrus) FROZEN STORAGE: EFFECT OF CATCHING SEASON AND COMMERCIAL PRESENTATION

Effects of Chicken Breast Meat on Quality Properties of Mackerel (Scomber japonicus) Sausage

This study was performed to evaluate the effects of chicken breast meat on the quality of mackerel sausages. The mackerel sausages were manufactured by additions of 5%, 7%, and 10% of chicken breast meat. The lightness of mackerel sausages showed no significant differences between the control and addition groups. The redness increased in a dose-dependent manner, but the yellowness decreased sig...

Monitoring the Freshness of Rainbow Trout Using Intelligent PH-sensitive Indicator During Storage

Background: The rainbow trout fish is susceptible to spoilage due to its high content of unsaturated fatty acids. It should be kept at low temperature to reduce microbial, enzymatic, and oxidation reactions. The purpose of this study was to design a packaging that contains a pH indicator for monitoring freshness of the rainbow trout fish during storage at refrigerator. Methods: The indicator co...

Steroidogenic and maturation-inducing potency of native gonadotropic hormones in female chub mackerel, Scomber japonicus

BACKGROUND The gonadotropins (GtHs), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are produced in the pituitary gland and regulates gametogenesis through production of gonadal steroids. However, respective roles of two GtHs in the teleosts are still incompletely characterized due to technical difficulties in the purification of native GtHs. METHODS Native FSH and LH were pu...

Three-dimensional analysis of finlet kinematics in the chub mackerel (Scomber japonicus).

Finlets, which are small non-retractable fins located on the body margins between the second dorsal and anal fins and the caudal fin of scombrid fishes, have been hypothesized to improve swimming performance. The kinematics of three posterior finlets of the chub mackerel, Scomber japonicus, were examined using three-dimensional measurement techniques to test hypotheses on finlet rigidity and fu...
